Abstract: The study shows small scale footing test results of silty clay reinforced with geosynthetics, where load is passed in the soil through a surface square footing having dimensions 75mm×75mm. In the research two types of planar reinforcements i.e., glasgrid and geotextile have been used. The results obtained from laboratory model footing tests reinforced with geosynthetics are presented and compared. The parameters analysed in the study includes the vertical spacing of first reinforcement layer from footing base (u), optimum depth of effective reinforcement (d), number of geogrid layers (N). Scanning electron microscopic (SEM) study also performed to observe the failure behavior of geosynthetic during the testing. The experimental results indicate that soil reinforced with geosynthetic increases the load carrying capacity of footing and the performance of glasgrid at lower settlement is better than geotextile in development of bearing capacity of foundation soil. Optimum spacing between base of footing and first reinforcement layer (u) is found to be 0.34B for both the reinforcements. Depth of effective reinforcement (d) was observed at 1.36B and 1.02 B for glasgrid and geotextile, respectively.
